Abstract :
An efficient structure to excite the fundamental mode in single-mode slab waveguides is proposed. The configuration consists of a tapered waveguide with nonlinear cladding. The numerical results show that the configuration is less sensitive to the offset between coupled waveguides and an excitation efficiency of 92% or more can be obtained.
